Corporation Inc is a Sim City style Flash game in which you try to build an enormous corporation. You build offices, hire workers who push buttons for you,along with janitors who clean the place up at night and managers who beat the workers with a stick to get them to do their jobs more efficiently. It's very addictive; perfect for a day in which you do not want to work.

Here's a walkthrough, but you really should just play the game yourself.
